Applications of induction linac technology to heavy ion fusion

Description: Evaluation of the application of heavy ion accelerators to ignite d-t pellets in a thermonuclear reactor is discussed. Accelerator design requirements considered include transport-limited current, beam injection conditions, and pulse bunching and focusing characteristics. The desirability of resonant and non-resonant accelerating structures is comparatively examined. The required power system switch tubes are discussed. It is concluded that heavy ion accelerators could offer a promising solutio… more

Scoping Report on Various Salt Mines in the United States

Description: One of the most important factors in isolating the demonstration waste storage site is an adequate number of shafts to insure proper ventilation. Proper ventilation will require that the air exhausted from the storage area pass directly to the upcast air shaft. Those mines reported by this scoping contract generally conform with the two shafts per mine requirement of MESA. Three of the mines reported on have more than two shafts. Several of the mines can have additional shafts drilled in time t… more

Pacific Northwest Laboratory Report on Fusion Energy Research, April 1977 - June 1977

Description: The development of economic data for fusion power plants continued in a study estimating the potential impact of a shortage of materials important in fusion plant construction. In studies developing heat transfer and fluid flow design tools for fusion reactor blankets, preconceptual design studies were initiated to identify the potential design limits of water cooling in the first wall of Tokamak Next Step (TNS) concepts. In surface effects research clean gold samples were irradiated in the Uni… more

Preliminary report on the promise of accelerator-driven natural-uranium-fueled light-water-moderated breeding power reactors

Description: A new concept for a power breeder reactor that consists of an accelerator-driven subcritical thermal fission system is proposed. In this system an accelerator provides a high-energy proton beam which interacts with a heavy-element target to produce, via spallation reactions, an intense source of neutrons. This source then drives a natural-uranium-fueled, light-water-moderated and -cooled subcritical blanket which both breeds new fuel and generates heat that can be converted to electrical power.… more

Turbulent interchange in triangular array bare rod bundles

Description: Bulk mixing coefficients were measured for single plane water flow in a simulated rod bundle with a pitch to diameter ratio of 1.10. A tracer technique employing Rhodamine B as the tracer and measuring fluorescence was used. Isokinetic sampling was achieved by using a pressure balance method. The results were corrected for both entrance effects and diversion crossflows. The results showed a change in Reynolds number behavior as the laminar sublayer began to ''choke'' the turbulent mixing. This,… more

Flash hydropyrolysis of coal. Quarterly report No. 2, April 1--June 30, 1977

Description: With the combination of low hydrogen to coal ratio, high coal feed rate and larger total quantity of coal fed, considerable liquid product is being condensed and collected. Experimental runs conducted at 750/sup 0/C and 800/sup 0/C at pressures up to 3000 psi of hydrogen show overall hydrocarbon yields and particularly gaseous hydrocarbon yields to increase with pressure to approximately 60 percent at 3000 psi. At 750/sup 0/C approximately one third (20 percent) of this yield is in the form of … more

Form-stable crystalline polymer pellets for thermal energy storage. Phase 1

Description: The objective of this project was to develop a form-stable, crystalline polymer pellet TES bed material, useful in the 120 to 140/sup 0/C temperature range suitable for solar absorption air conditioning applications. This objective was achieved with a Si-O-Si crosslinked HDPE pellet material, demonstrated to have a high heat of fusion value (46 cal/g, approximately 98% of the HDPE's heat of fusion value prior to crosslinking). Further, on melt/freeze cycling of these TES pellets through 400 cyc… more

I. Low frequency noise in metal films at the superconducting transition. II. Resistance of superconductor - normal metal- superconductor sandwiches and the quasiparticle relaxation time

Description: Measurements of the noise power spectra of tin and lead films at the superconducting transition in the frequency range of 0.1 Hz to 5k Hz are reported. Two types of samples were made. Type A were evaporated directly onto glass substrate, while Type B were evaporated onto glass or sapphire substrate with a 50A aluminum underlay. The results were consistent with a thermal diffusion model which attributes the noise to the intrinsic temperature fluctuation in the metal film driven with a random ene… more

Ion implantation range and energy deposition codes COREL, RASE4, and DAMG2

Description: The FORTRAN codes COREL, RASE4 and DAMG2 can be used to calculate quantities associated with ion implantation range and energy deposition distributions within an amorphous target, or for ions incident far from low index directions and planes in crystalline targets. RASE4 calculates the projected range, R/sub p/, the root mean square spread in the projected range, ..delta..R/sub p/, and the root mean square spread of the distribution perpendicular to the projected range ..delta..R/sub perpendicu… more

Measurement of pressure, fluidized bed level, and density in the Synthane Pilot Plant coal gasifier

Description: Fluid bed densities and levels are usually obtained from measurement of differential pressures between taps with a known vertical separation. Historically, this measurement has been difficult in high pressure coal gasification processes primarily due to plugging of the pressure taps and process instrument tubing. Likewise, the achievement of accurate and reliable pressure and differential pressure recordings is affected by similar circumstances. These typical problems were experienced at the SY… more

Effects of fill gas composition and pellet eccentricity. [BWR]

Description: Data and an analysis are presented showing that when the operating pellet-cladding gap size of contemporary UO/sub 2/ fuel rods is carefully considered, the gap conductances are closely proportional to the thermal conductivities of the fill gases. Pellet-cladding gap eccentricity is shown to raise the gap conductance appreciably in cases of high thermal gradients across the gap. Ignoring the azimuthal heat flow can lead to an underestimation of the thermal time constant of the rod, resulting in… more

Low cost solar collector of a packed bed design

Description: Two solar collectors using a pebble bed design were constructed and tested using air as the heat exchange media. One collector had pebbles of metallurgical grade coke, and the other had a frothy volcanic material called scoria. The highly irregular surface of such vesicular material should increase the path distance for the air and the surface exposed cavities should give some honeycomb effect. Both should yield greater efficiency. Actual testing shows the efficiencies to be comparable with oth… more

Can the Sun replace uranium

Description: Two asymptotic worlds, one based on solar energy, the other based on nuclear energy, are compared. The total energy demand in each case is 2,000 quads. Although the Sun can in principal supply this energy, it probably will be very expensive. If the energy were supplied entirely by breeders, the nuclear energy system would pose formidable systems problems--particularly safety and proliferation. It is suggested that in view of these possible difficulties, all options must be kept open.

Effect of reduced boiler water temperature on cycle efficiency

Description: Tests were performed on a ''typical'' residential hot water boiler to evaluate the energy saving potential of reduced boiler water temperature. A significant reduction of annual fuel consumption was determined based on detailed efficiency measurements combined with the BNL Seasonal Performance Evaluation Computational Program. The energy saving has been attributed to reduced off-cycle heat losses resulting from the lower boiler operating temperature.

Development of ferromagnetic spinels for optical isolation at 10. 6. mu. m. Progress report, May 1, 1977--July 31, 1977

Description: An analysis of factors which influence the optical transparency of hot-pressed CdCr/sub 2/S/sub 4/ at 10.6 ..mu..m was made. It was found that multiphonon absorption, an intrinsic process, is the factor which limits the ultimate achievable absorption coefficient, ..cap alpha.., at 10.6 ..mu..m. Several extrinsic processes have also been found to affect the transmission of hot-pressed CdCr/sub 2/S/sub 4/. In sufficient concentration, oxygen appearing as SO/sub 4//sup 2 -/ or similar sulfate comp… more
